Context History (more history, all contexts)

Start Date Context Status Description
2023-05-10 hst_1076.pmap operational Delivery of new STIS CCD bias and dark reference files for CCD data taken between April 3 2023 and May 2 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16947 and 16949.
2023-05-05 hst_1075.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Apr 28, 2023, and should be used to calibrate ACS WFC observations taken between Mar 27, 2023 and Apr 28, 2023.
2023-04-19 hst_1074.pmap archived These WFC3 UVIS superbias, bia, files will affect all full-frame and subarray 1x1 binned UVIS data. The 2021 superbiases will affect data taken from January 1 - December 31 2021. The 2022 superbiases will affect all data taken after January 1, 2022. Currently, the automated calibration pipeline and Calibration Reference Data System only have WFC3 UVIS full-frame and subarray bias reference files up to a USEAFTER date of January 1, 2020. The automated pipeline should now use these reference files to perform bias subtraction on any 1x1 binned UVIS datasets obtained between the dates above because they represent the most accurate estimate of the residual bias level at the time of the science observation. The 2021 WFC3 UVIS superbias files were generated using bias exposures from the HST Cycle 28 and 29 monitoring programs 16414 and 16564. The 2022 WFC3 UVIS superbias files were generated using bias exposures from the HST Cycle 29 and 30 monitoring programs 16414 and 16967. More information regarding the method used to create UVIS bias calibration reference files can be found in I.Rivera, B.Kuhn, 2023. Additionally, the header of each reference file has a history section listing the datasets used to create each file. These are a delivery of new WFC3 UVIS postflash reference files for data taken after January 1st 2022. The process of creating these time dependent reference files are described in detail in WFC3 ISR 2023 01. Currently the pipeline uses the 2021 post-flash reference files on data taken in 2022 and 2023, this update will apply the post-flash reference file from 2022 to that data instead. They were made from Cycle 29 and 30 from proposals 16570 and 16982.
2023-04-14 hst_1072.pmap archived Updating the STIS CCD G750L cenwave 7751 photometric calibration table, PHOTTAB, to use the 2020 March update corresponding to the CALSPECv11 models. Typical flux changes for this mode are expected to be of order less than one percent. For more details, see the upcoming April 2023 STAN.
